The world seems to be run by people who have great ideas and the courage to follow through on them. That seems to be the case with Yahoo! Finance’s list of “How to be a Millionaire by Age 25.” Featured among the list are some familiar names – Mark Zuckerberg, the facebook founder whose life has recently been picked apart in The Social Network and Michael Dell – the man who helped make personal computers common in homes. Catherine Cook, founder of another hit social networking site and Carbonfund.org partner myyearbook.com, earned her first million by 18 by designing a hit website with over 20 million members. Catherine has brought people together to share pics, play games, chat, take quizzes, go on blind dates, and… donate to some great Causes. By interacting on myyearbook.com, members can earn “lunch money” which they can then use to offset carbon emissions in the atmosphere by supporting Carbonfund.org’s third-party validated renewable energy projects. Catherine says if you’ve got a great idea to make a million, “Stop just thinking about it, and make it happen.” She also has advice for young people: “When you’re young is the best time to start your own business, as you do not have the responsibilities you will have when you’re older. The worst that can happen if you fail now is that you have firsthand experience to make your next venture a success.” Once you get there, remember to follow Catherine’s lead by helping the planet too!
